Otterly.AI
- Google AI Mode and Gemini cost $9, $59 or $149 a month each by plan, and Claude $29, $109 or $439, so all seven engines on Standard add $227 a month.

Key features
Known Agents
- Agent Analytics
- Lists the crawlers, scrapers and AI agents visiting a site in real time, with traffic trends, pages visited, sessions, errors and robots.txt violations per agent.
- AI chat referral tracking
- Counts human visits that come from ChatGPT, Claude, Gemini, Copilot, Perplexity, DeepSeek and other AI chats, kept apart from bot traffic.
- Automatic robots.txt
- Serves a robots.txt that blocks or allows agents by category and updates itself as new bots are found; the WordPress plugin can block bots that ignore it.
- Agent Identification API
- Identifies and verifies the agent behind an incoming request from your own code, for setting access rules by verified identity.
- Server-side collection
- Data is sent from the server, CDN or backend rather than a browser script, so it still works when browser analytics are blocked.

Otterly.AI
- Daily prompt monitoring
- Tracks set prompts every day and reports brand mentions, coverage, share of voice and sentiment per engine, in more than 70 countries.

- AI prompt research
- Suggests prompts customers are likely to ask AI search tools about a brand or topic, as a starting set to monitor.

- Agent Analytics
- Reports AI agent and crawler visits to your site from server log files you upload.
- API, MCP and Looker Studio
- An API and MCP server give programmatic access to the data; the Looker Studio connector comes with Standard and above.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
